This commit resolves the native compilation failure when using Java 22 with GraalVM. The issue was caused by SLF4J service providers being initialized at runtime instead of build time. Changes: - Add SLF4J RuntimeHints to SpringAiCoreRuntimeHints for native compilation - Register NOP_FallbackServiceProvider and SubstituteServiceProvider for build-time initialization - Add comprehensive tests for all registered types including SLF4J This fix ensures compatibility with both Java 21 and Java 22 for native image compilation.
